Very Nice. Thanks for the follow up. I may look into that at some point.That looks like it will work great. I did end up going with a lower temp snap disc and it has been working perfectly. Also when I took the old snap disc out it has rivets holding it in thus making a small gap from bottom of fire box and disc. On the new disc I ground down some of the new rivets so it was in full contact with the bottom of the fire box
